Ovt84,
I have used 45.0 grains of Hunter with a variety of bullets in the 140-grain range since buying my first Creedmoor in 2010. Not a one has shown the slightest sign of high pressure, and both velocity and accuracy have generally been good to excellent.
The only downside might be that Hunter isn't as temperature-resistant as some other powders, though its by no means overly so.
